So I have an increase exhaust sound that I’d explain it has a fart around 3K RPM. It will continue to do it until I get past 3K RPM (up or down). The only thing I changed was the 91 stage 2 to the 93 stage 2 and I’m at a lower elevation. Has anyone else ran into this issue? Should I be worried about this? Any suggestions?
